With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new clamping device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 6, the clamping assembly 10 generally comprises a bottom disk 12 that may be positioned proximate the stack of pages 14. The stack of pages 14 may be paper pages of any conventional design. Additionally, the bottom disk 12 may have a diameter between 12 mm and 25 mm. A lip 16 is coupled to and extends upwardly from a top side 18 of the bottom disk 12. The lip 16 is coextensive with an outer edge 20 of the bottom disk 12.

A bottom engaging disk 22 is coupled to a top edge 24 of the lip 16 on the bottom disk 12. An outer edge 26 of the bottom engaging disk 22 is coextensive with the lip 16 on the bottom disk 12. Additionally, a top surface 28 of the bottom engaging disk 22 is textured. A tube aperture 30 extends through a top side 32 and a bottom side 34 of the bottom engaging disk 22 proximate the outer edge 26 of the bottom engaging disk 22. The tube aperture 30 may have a diameter between 6 mm and 12 mm.

A tube 38 extends downwardly through the tube aperture 30. Moreover, a bottom end 40 of the tube 38 is coupled to the top side 18 of the bottom disk 12. A shaft 44 is slidably positioned within the tube 38. Further, a bottom end 46 of the shaft 44 is positioned proximate the bottom end 40 of the tube 38. A retaining groove 48 extends around an entire perimeter of an outer surface 50 of the shaft 44 proximate the bottom end 46 of the shaft 44. Continuing, a first retaining ring 52 is positioned within the retaining groove 48.

An inner surface 54 of the tube 38 is flared outwardly proximate a top end 56 of the tube 38. A flared portion 58 of the inner surface 54 of the tube 38 has a diameter that is greater than a diameter of a remaining portion 60 of the inner surface 54 of the tube 38. A second retaining ring 62 is positioned within the tube 38 so the shaft 44 extends through the second retaining ring 62. The second retaining ring 62 abuts a top edge 64 of the flared portion 58 of the inner surface 54 of the tube 38 so the second retaining ring 62 is retained within the tube 38. A primary spring biasing member 66 is positioned within the tube 38. The primary spring biasing member 66 is positioned between the top side 18 of the bottom disk 12 and the bottom end 46 of the shaft 44. Lastly, the primary spring biasing member 66 biases the shaft 44 upwardly in the tube 38 so the first retaining ring 52 abuts the second retaining ring 62.

A top disk 68 is provided. An outer edge 70 of the top disk 68 has a flat portion 72 so the top disk 68 forms a circle segment. The top disk 68 may have a diameter between 12 mm and 25 mm. Further, the flat portion 72 of the outer edge 70 of the top disk 68 defines a chord of the circle segment that may have a length between 8 mm and 20 mm. A lip 74 is coupled to and extends upwardly from a top side 76 of the top disk 68. The lip 74 is coextensive with the outer edge 70 of the top disk 68.

A flat portion of the lip 75 on the top disk 68 is coextensive with the flat portion 72 of the outer edge 70 of the top disk 68. Further, the flat portion of the lip 75 is spaced inwardly away from the flat portion 72 of the outer edge 70 of the top disk 68.

The primary shaft aperture 78 may have a diameter between 4 mm and 10 mm. The shaft extends 44 upwardly through the primary shaft aperture 78 in the top disk 68. Moreover, the top disk 68 is coupled to the shaft 44. The bottom side 82 of the top disk 68 is textured.

A retainer 84 is provided. A rounded portion 86 of the retainer 84 is coupled to a second end 88 of a straight portion 90 of the retainer 84. Moreover, the retainer 84 has a T-shape. A first end 92 of the straight portion 90 of the retainer 84 is hingedly coupled to the top side 76 of the top disk 68. The straight portion 90 of the retainer 84 extends outwardly through an opening 94 in the lip 74 on the top disk 68. Moreover, the rounded portion 86 of the retainer 84 is positioned outside of the lip 74 on the top disk 68. The rounded portion 86 of the retainer 84 may have a width between 6 mm and 18 mm. Further, the straight portion 90 of the retainer 84 may have a length between 4 mm and 16 mm.

A secondary shaft aperture 96 extends through a top side 98 and a bottom side 11 of the straight portion 90 of the retainer 84. The secondary shaft aperture 96 may have a diameter between 4 mm and 10 mm. Additionally, the shaft 44 extends upwardly through the secondary shaft aperture 96 in the straight portion 90 of the retainer 84. A secondary spring biasing member 13 is positioned around the shaft 44. The secondary spring biasing member 13 is positioned between the bottom side 11 of the straight portion 90 retainer 84 and the top side 76 of the top disk 68. Moreover, the secondary spring biasing member 13 biases the retainer 84 into a retaining position. An outer edge 15 of the secondary shaft aperture 96 in the straight portion 90 of the retainer 84 engages the outer surface 50 of the shaft 44.

A cover 17 is coupled to a top edge 19 of the lip 74 on the top disk 68 so an outer edge 21 of the cover 17 is coextensive with the lip 74 on the top disk 68. A release 23 is provided. An outer edge 25 of the release 23 has a flat portion 27 so the release 23 forms a circle segment. Continuing, the outer edge 25 of the release 23 defines a chord of the circle segment that may have a length between 8 mm and 20 mm. The release 23 is operationally coupled to the top disk 68. Continuing, the flat portion 27 of the outer edge 25 of the release 23 abuts the flat portion 72 of the outer edge 70 of the top disk 68. The release 23 and the top disk 68 form a complete circle.

A lip 29 is coupled to and extends upwardly from a top side 31 of the release 23. The lip 29 on the release 23 is coextensive with the outer edge 25 of the release 23. A cover 33 is coupled to a top edge 35 of the lip 29 on the release 23. The cover 33 is coextensive with the lip 29 on the release 23. Continuing, the rounded portion 86 of the retainer 84 is positioned with the release 23. An outer edge 37 of the rounded portion 86 of the retainer 84 is coextensive with an inner surface 39 of the lip 29 on the release 23.

A flat portion of the lip 29 on the release 23 is coextensive with flat portion 27 of the outer edge 25 of the release 23. An opening in the flat portion of the lip 29 on the release 23 receives the rounded portion 86 of the retainer 84. Continuing, the flat portion of the lip 29 on the release 23 is spaced rearwardly from the flat portion 27 of the outer edge 25 of the release 23. The flat portion of the lip 29 on the release 23 may be spaced a distance between 1 mm and 2 mm from the flat portion of the lip 29 on the release 23.

An adhesive layer 43 completely covers a bottom side 45 of the bottom disk 12. A coupler 47 is coextensively coupled to the adhesive layer 43. The adhesive layer retains the coupler on the bottom side 45 of the bottom disk 12. Continuing, the coupler 47 may be a hook and loop fastener of any conventional design. Alternatively, the coupler 47 may be a magnet of any conventional design. The coupler 47 engages a support surface so the assembly 10 is retained on the support surface.

In an alternative embodiment, the bottom disk 12 may be coupled to a clip board 49. A disk well 51 extends rearwardly into a front side 53 of the clip board 49 proximate a top edge 55 of the clip board 49. Moreover, the disk well 51 is positioned proximate a center 57 of the top edge 55 of the clip board 49. The bottom disk 12 is positioned within the disk well 51. Continuing, a hanging aperture 59 extends through the front side 53 and a back side 61 of the clip board 49. The hanging aperture 59 is positioned between the disk well 51 and the top edge 55 of the clip board 49. Finally, the hanging aperture 59 may insertably receive a support 63 so the clip board 49 may be hung from the support 63.

In use, the stack of pages 14 is selectively positioned between the top 68 and bottom 12 disks. The top disk 68 is urged downwardly so the stack of pages 14 is compressed between the 28 top surface of the bottom engaging disk 22 and the bottom side 82 of the top disk 68. The retainer 84 is positioned in a retaining position so the stack of pages 14 is retained between the top 68 and bottom 12 disks. Continuing, the release 23 is selectively depressed so the retainer 84 is urged into a releasing position. The shaft 44 freely moves in the secondary shaft aperture 96 in the retainer 84. Moreover, the primary spring biasing member 66 biases the top disk 68 upwardly away from the stack of pages 14 so the stack of pages 14 are removable from the assembly 10.
